Abstract:
:Microcystis aeruginosa is a common cyanobacterium in water blooms that appear widely in nutrient-rich, fresh, and brackish waters, and its toxic blooms cause the death of domestic animals. The administration of a crude toxic cell extract of M. aeruginosa K-139 to mice can produce tumor necrosis factor (TNF) and prompt severe physiological disturbances, especially liver damage, which can lead to death. The in vitro production of TNF-alpha by peritoneal macrophages was observed after stimulation with the cell extract or the purified toxin from K-139 cells. The expression of a TNF-alpha mRNA was also detected in spleen cells and peritoneal macrophages after stimulation with the cell extract. However, a previous injection of rabbit anti-murine TNF-alpha serum could prevent the liver damage to some extent and protect the mice from death. These findings indicate the involvement of TNF in microcystin shock.
